Nanomaterials of different chemical compostions, such as liposomes, micelles or inorganic nanoparticles hold tremendous potential as carriers for drugs to target cancer cells. The effectiveness of drug delivery systems can be attributed to their small size, reduced drug toxicity, controlled time release of the drug and modification of drug pharmacokinetics and biological distribution.

This paper presents a review of zinc oxide (ZnO) as nano material and device. ZnO has gained substantial interest in the research area of wide band gap semiconductors due to its unique electrical, optical and structural properties. Recently, ZnO as nano material generates much interest among researchers and technologists and have been used in many devices such as UV photodetectors, light emitting diodes, solar cells and transistors. Moreover, a brief overview on ZnO recent advances on... Topics: ZnO, Nanomaterials, Nanodevices, Nanowires, Nanorods.
Nanotechnology in science, engineering and technology represents the study of phenomena and the manipulation of materials at nanoscale, which is about 1 to 100 nanometers. At nanoscale, the properties of materials are dramatically improved from the properties of individual atoms due to increase in relative surface area and quantum effects. The construction industry is a new field for nanotechnology and is growing rapidly for the last few years. Nanotechnology based products can improve the...

A simple chemical reduction method is followed to grow ZnSe nonomaterials at room temperature with different duration of growth time. The dispersed samples are characterized using electron diffraction techniques. Simultaneously optical absorption, photoluminescence and longtime photorelaxation of these samples are studied at room temperature. Nanomaterials are obtained with different shape. An increase in band gap is observed in each case as compared to bulk ZnSe. Dimension of nanomaterials... Topics: Microstucture, Nanomaterials ZnSe, Optical Properties, Optoelectrical Properties
This article reports how the significant it is to recognize the optimal annealing circumstances when electrospun composite fibers are heated to obtain ceramic nanofibers in proper characteristics. Polyvinylpyrrolidone (PVP) and ammonium metatungstate (AMT) nanoscaled fibers have been synthesized by electrospinning aqueous solutions of PVP and AMT. The as-spun fibers and their annealing were studied by scanning electron microscope (SEM) and Raman measurements. The 500 – 600... Topics: Nanomaterials, Nanofiber, Tungsten Oxide, Raman Scattering
CdTe nano particles are grown by varying temperature and keeping ratio of reagent constant. The samples are characterized structurally and optically. An increase in band gap is observed compared to bulk CdTe in each growth condition. Also the nanorods formation is found to be favourable at particular temperature. An attempt is made to correlate the structural and optical properties Topics: Synthesis of Nanomaterials, Structural Properties, Optical Properties
We are glad to present another NanoWiki compilation, following 'Balancing the promises' and 'Engines On'. This year we chose the subject of Nanoparticles Before Nanotechnology simply because we were suspicious that nanoparticles are too often, in scientific and non-scientific circles, perceived as invented, while we think they should be understood as discovered. Nanomaterials are claimed to be so new that people become scared. However, before nanotechnology, one can find nanoparticles in the...

Polylactic acid (PLA) is a highly promising material for its biodegradability, nontoxicity, high mechanical strength, ability to be absorbed into human body and its non-toxic biodegradation products. However, when it comes to bone tissue engineering, PLA has major drawbacks such as low cell adhesion caused by its hydrophobic property, and inflammatory reactions in vivo due to its degradation product, lactic acid. One pragmatic solution for the mentioned problems is the introduction of bioactive... Topics: Bone Tissue Engineering, Bioactive Ceramic Nanomaterials, Polylactic Acid
Hardcoatings of WC/12Co and Al2O3/13TiO2, produced by High Velocity Oxy-Fuel (HVOF) and High Energy Plasma (HEP) spraying, have been investigated. In HVOF spraying, nanostructured WC/Co coatings experience more extensive decarburization than conventional coatings, whereas in HEP spraying, just the opposite effect occurs. This is explained in terms of the influence of temperature on the decarburization mechanism. In the Al2O3/13TiO2 case, HEP spraying generates a metastable coating, due to rapid...
